Bioclimatic Double-Skin Façades

Visually enriched with over 250 photographs and drawings, Bioclimatic Double-Skin Façades is an essential reference guide for understanding the types and functions of double-skin façades. Author Mary Ben Bonham examines the history and continuing potential of double-skin architecture, informing on the variety of approaches possible and advising a rigorous integrated design process leading to application. Featuring a wide selection of architectural examples, the book will be of interest to professionals and students within the fields of architecture, engineering, and construction. Characterized by a buffer-like air space between two glazed building skins, double-skin windows and façades aim to improve building comfort and energy performance. Double skins introduce complexity and initial costs, yet significant buildings in locations around the globe continue to select this approach. In addition to exploring motivations, benefits, and cautions for designing with double skins, the book provides a primer on fundamental façade design concepts and strategies for control of thermal, luminous, and acoustic environments. Chapters also address alternative types of high-performance façades and implications for each phase of façade design and construction. Bioclimatic Double-Skin Façades promotes bioclimatic design that is inspired by nature, measured in performance, and uniquely adapted to climate and place. In-depth case studies illustrate how double-skin façades have been adapted to a range of climates and cultural settings: Marseille Library and Grenoble Courthouse in France, Cambridge Public Library in Massachusetts, Manitoba Hydro Place in Canada, and the Pearl River Tower in China.

Bioclimatology and Biogeography of Africa

Covering an area of over 130 million km2 spanning the Mediterranean, equator and tropics, the African continent features a spectacular geographic diversity. Consequently, it is characterised by extremely variable climatic, edaphic and ecological conditions, associated with a wide range of natural vegetation and wildlife, as well as human population density, crops and livestock. In this book, Henry Le Houérou presents his bioclimatic and biogeographic classification of Africa. The extensive data provide the basis for comparisons between various African regions, and with regions on other continents such as Latin America or the Indian subcontinent. The results constitute a rational basis for national, regional and sub-regional rural development planning, and for agricultural research dealing with aspects such as plant and animal introductions, the extrapolation or interpolation of experimental or developmental findings, and ecosystems dynamics. Possible problems of applications are also examined.

Bioclimatology and Natural Hazards

Anthropogenic influences to the earth's system, including the atmosphere, hydrosphere, biosphere, cryosphere and lithosphere, represent a serious challenge to our planet's ecosystems and natural environments. Bioclimatology, hydrology, bio-hydrology and eco-physiology are important scientific research areas with wide application to environmental protection, forestry, agriculture and water management, and protection against natural hazards including droughts, floods, windstorms, weather extremes, and wild fires. Bioclimatology helps to better understand the causes and impacts of natural hazards and how to prevent them. Improved knowledge of natural hazards is a vital prerequisite for the implementation of integrated resource management. It provides a useful framework for combating current climate variability and for adapting to ongoing climate change. This book presents research on the interactions between meteorological, climatological, hydrological and biological processes in the atmospheric and terrestrial environment. It highlights a spectrum of topics associated with climate change and weather extremes and their impact on different economic sectors. The contributing authors come from renowned scientific research institutions and universities and specialise in issues of climate change, soil-plant-atmosphere interactions, hydrologic cycle, ecosystems, biosphere, and natural hazards.

The Bioclimatology of Frost: Its Occurrence, Impact and Protection (Advances in Bioclimatology #2)

The economic costs of frosts in agriculture and horticulture in many parts of the world can be very significant. Reports in the media include accounts on how frosts have devastated coffee crops in Brazil or in Papua New Guinea, and how frosts have seriously damaged the Florida citrus industry. Frost may cause losses in current harvests or a decline in future yields through more permanent damage to trees and bushes. Damaging frosts may occur as infrequent, short-term events with sub-zero temperatures or with unusually severe winter temperatures which extend over long periods. In this book we have aimed at providing a comprehensive review of recent advances in the area of frost research. The stimulus for writing this book has come from the recognition that there is a shortage of recent texts which deal exclusively with the bioclimatology of frost. Bioclimatology deals with the relations between climate and life and the present text is particularly concerned with the effects of low temperatures on plants. Our purpose has been to assist researchers, engineers, extension officers and students in understanding the physical aspects of frost occurrence and frost distribution as well as the biological and phenological aspects of frost damage and to provide an overview of direct and indirect methods of frost pro­ tection and prevention.

Biocommunication in Soil Microorganisms (Soil Biology #23)

Communication is defined as an interaction between at least two living agents which share a repertoire of signs. These are combined according to syntactic, semantic and context-dependent, pragmatic rules in order to coordinate behavior. This volume deals with the important roles of soil bacteria in parasitic and symbiotic interactions with viruses, plants, animals and fungi. Starting with a general overview of the key levels of communication between bacteria, further reviews examine the various aspects of intracellular as well as intercellular biocommunication between soil microorganisms. This includes the various levels of biocommunication between phages and bacteria, between soil algae and bacteria, and between bacteria, fungi and plants in the rhizosphere, the role of plasmids and transposons, horizontal gene transfer, quorum sensing and quorum quenching, bacterial-host cohabitation, phage-mediated genetic exchange and soil viral ecology.

Biocultural Landscapes: Diversity, Functions and Values

This book is devoted to the cultural and biological dimensions and values of landscapes, linking the concepts of biodiversity, landscape and culture and presenting an essential approach for landscape analysis, interpretation and sustainable dynamics.Early chapters explore the concepts and values of biocultural landscapes, before addressing the methodology to identify the relationship between biological and cultural diversity. The volume continuous with a series of case studies and with an exploration of the key role of biocultural diversity in contemporary landscape ecology.Readers will learn the importance of landscapes for different fields of natural and human sciences and are confronted to the trans-disciplinary nature of the landscape concept itself. A hierarchical approach to landscapes, in which they are composed of interacting (eco)systems, is shown to be essential in recognizing their emergent properties.In this work, the biocultural values of landscapes are explored through their diversity in geographical scopes, methodological approaches and conceptual assumptions. Authors from Asia, Europe and North-America present diverse research experiences and views on biocultural landscapes, their pattern, conservation and management.Landscape ecologists will find this work particularly appealing, as well as anyone with an interest in sustainable landscape development, nature conservation or cultural heritage management.This volume is the outcome of a symposium on “Biodiversity in Cultural Landscapes”, organized in the framework of the 8th IALE World Congress, held in Beijing in 2011.

Biocultural Rights, Indigenous Peoples and Local Communities: Protecting Culture and the Environment (Routledge Explorations in Environmental Studies)

This volume presents a comprehensive overview of biocultural rights, examining how we can promote the role of indigenous peoples and local communities as environmental stewards and how we can ensure that their ways of life are protected. With Biocultural Community Protocols (BCPs) or Community Protocols (CPs) being increasingly seen as a powerful way of tackling this immense challenge, this book investigates these new instruments and considers the lessons that can be learnt about the situation of indigenous peoples and local communities. It opens with theoretical insights which provide the reader with foundational concepts such as biocultural diversity, biocultural rights and community rule-making. In Part Two, the book moves on to community protocols within the Access Benefit Sharing (ABS) context, while taking a glimpse into the nature and role of community protocols beyond issues of access to genetic resources and traditional knowledge. A thorough review of specific cases drawn from field-based research around the world is presented in this part. Comprehensive chapters also explore the negotiation process and raise stimulating questions about the role of international brokers and organizations and the way they can use BCPs/CPs as disciplinary tools for national and regional planning or to serve powerful institutional interests. Finally, the third part of the book considers whether BCPs/CPs, notably through their emphasis on "stewardship of nature" and "tradition", can be seen as problematic arrangements that constrain indigenous peoples within the Western imagination, without any hope of them reconstructing their identities according to their own visions, or whether they can be seen as political tools and representational strategies used by indigenous peoples in their struggle for greater rights to their land, territories and resources, and for more political space. This volume will be of great interest to students and scholars of environmental law, indigenous peoples, biodiversity conservation and environmental anthropology. It will also be of great use to professionals and policymakers involved in environmental management and the protection of indigenous rights.

The text covers numerous topics, including: bioavailability, biodegradation of various pollutants, microbial community dynamics, properties and engineering of important biocatalysts, and methods for monitoring bioremediation processes. Microbial processes are environmentally compatible and can be integrated with non-biological processes to detoxify, degrade and immobilize environmental contaminants.

Biodegradation and Persistence (The Handbook of Environmental Chemistry #2 / 2K)

Biodegradation is a key phenomen among environmental processes. Low degradation rates lead to the persistence of chemicals in the environment and, as a consequence, to delayed or long-term effects, which may be even unknown by now. In this volume the editor has pulled together the newest results of research in biodegradation and persistence of potential environmentally harmful substances and the complex process involved. The main focus is on the microbial degradation, the evolution and predictability of the respective pathways and their impact on bioremediation. Additional chapters deal with sewage treatment plants, the impact of toxicants on impaired biodegradation, and with the need of a more realistic view on fate and behaviour of chemicals in the environment.

Biodegradation of Azo Dyes (The Handbook of Environmental Chemistry #9)
